1- lowing is 'a speciiication.

' vA further object vof the-invention is to My'einventlon relates tov wl'ndowisashlifts and ventilators; and its' primary-obj eet iis to" provide 'ai combinedyentilator .and sash-lift` which is a vv decided improvement upon the exe isting art :and which is Simple v of 'construcfvv 1 ftio'n, cheap to. manufacture, durable, andrei-1' is: y

iicient.

vide a combined ventilator and sash liit" --whichis composed of few parts lso arranged and associated as not to .be liable to broken or ino erative.

With the above and other become the invention. .consists in the .arrangement [and combination of parts hereinafter fully preferred described, claimed, and illustrated in the accompanying drawings', which `disclose the forms .of my-inventi on,,fa1.id in Which-.-v y 'y i yFigure l1 is.

' mentary portion of the bottom rail of the lower window-sash, Ishowing the applicationv y of my im roved combined ventilatorl and.

I sash-lift. ig. 2 is a central transverse sec-f" tion thereof.. Fig. 3 is a detail plan view of the combined ventilator and sash-lift, the closure being removed; and Fig. is a detail y plan viewof the closure.

.f I l reference- Refen'ingvto `the drawings b? d sin icating numerals, like reference-numera like parts in the several-figures@ designates the bottom rail'f of a lower window-sash,v

which is provided with an opening 2, extending transversely of .the rail. A rec'ess2a is formed in the inner face -,of the bottom'rail and communicates adjacent one of its ends withgsaid'opening. 3 designates the sashlift, consisting of an. oblong casin 4, which is inserted in sald recess and which as projecting fromits outer` edges a flan'gef', adaptedl to engage the inner face of the bottom rail,

the said casing '4 being further provided at its ends witn openings 6, through which screws 6 or other fastening means pass to engage the lottom rail .to securely retain -the sash-lift in applied position. When it is de- .HARLQ aptes, siding at lg/(Elli Adams,in the county of Berk-'ig shire and State of Massachusetts,l have. in-"v vvented new and useful Improverrigei its'in`l Window- Sash Ventilators, of which theifol-j objects in view la perspective view of adzirag- Patented Maren' 20,1996.

'1 sired to raise 'or lower the` sash, the ,iingers 'of 3the' operator are inserted into the casingand i upward or downwardv pressure exerted, the

casing thus'acting -as-a sash-liit. The-back wall 7 of the-casing 4 is provided at one of'itsI .ends with an opening 8, 'whichr'egisterswith thefopeningg2, whereby airv may enter the room. -This'o ening is controlled b means@ of an elongate closure-plate 9, whic is slid- .'ably mounted in ways'iormed at the top and bottom of the sash-lift b the Aback Wall 7 and jections `10, the-latter being provided b 1npunching the upperand lower walls o thecasing adjacent to said back wall..4 The clo sure is designed to be operated by means of a handle 11, struck up from the closure 9 andbent at4 right anglesy thereto and arranged v i wholly within-the casing'. This -manner of constructing vthe closureand handle permits ofthe closure and-handle being. struck up from asin le blank of metal, thereby greatly reducing"t e cost ofmanufacture land simplifying the construction of the closure and its operating means. It will also be observed that the describedconstruction of the casing results in the formation of a chamber to receive thel,

sliding closure Qand for the reception ofthe iingers-of the operator ,in raising I"and lowerin the window, thetop and bottom walls 'of sai casing, which-are comparatively wide, proding upper and lower bearing portions for engagement by the fingers, whereby upward o'ljfl'dpwnward pressuremay be conveniently exerted to force the sash'to openior closed position. By this means all of the operative parts of the device are inclosed and protected from injury, thus obviating the necessity of employing projecting iinger ypieces or ortions whichare liable to be broken or ot er- -wise injured." A

Inorder to.prevent n foreign substances lfrom entering the room t ough the openings 2 and 8, I mount within the outer end of the opening 2 a tube 12, having extending thereacross ascreen'13.. The outerextremity of the tube 12 is bent outwardly and inwardly to provide an annular shoulder and an annular recess A14:. The recess is adapted to receive the edges of the screen 13, after which the extremities of the tube are depressed to clam the screen in applied position.` The shou der engages the outer face of the rail I to limit the inward movement of the tube 12 65 JVplurality 0f iDWardlyirected spurs or prowithin the 0 'ming 2, and Said tube may be securely hel in applied position by any suitable means or in any suitable manner.

Having thus described the invention, what e' is claimed as new is- In a window-sash and ventilator, the com bination with the bottom rail of a sash, said railhaving a transverse opening and a longitudinal recess 1n its inner face communlcatlng adjacent one of its ends with sald 0 ening, of an oblong casing occu ying sai recess, acting as a sash-lift and aving a back wallformed adjacent one of its ends with an opening registering with the opening in the sisma FRANK.
